Paperless Voting Machines?

How is possible that modern voting machines can have no paper trail? Without a paper record of the votes it would seem these machines are easily subject to tally problems, either from machine failure or even deliberate fraud. Take this quote from the Brennan Center for Justice, ""These machines are vulnerable to attack. That's the bad news. The good news is that we know how to reduce the risks and the solutions are within reach."

The solution is to require that voting machines have paper trails. We need to ask our representatives to support H.R. 550 -- the Voter Confidence and Increased Accessibility Act.
